Precision uv laser marking source laser engraving, make masks more assured

With the recent outbreak of the epidemic, masks have become a daily necessities at this stage. However, the huge demand gap has made some unscrupulous traders take advantage of it, and a large number of inferior masks have entered the market. Fake masks not only have no protective effect, but also have the risk of contamination due to substandard production environment hygiene, which is very harmful to personal health. To identify real and fake masks, the direct method is to check the laser anti-counterfeiting marks and use RFH laser laser engraving machine.

For boxed 3M N95 series masks, it can be identified by the anti-counterfeiting label on the mask box. The labels of real masks will change color from different angles, while the labels of fake masks will not change color. For bulk 3M N95/KN95 series masks, the authenticity can be identified by observing the fonts on the masks. The real 3M masks are marked by a laser engraving machine, and the fonts have diagonal lines, while the fake ones are printed with ink and have dots (traces of uneven ink).

Laser laser engraving, make masks more assured

In fact, the anti-counterfeiting technology of RFH laser engraving machine can not only be used for the authenticity identification of masks, but also plays a huge role in the packaging anti-counterfeiting and traceability of food, medicine, tobacco, beauty, electronic products and other fields. It can be said that laser Anti-counterfeiting marking has been integrated into all aspects of our lives. What advantages does it have over traditional methods?

The principle of RFH laser engraving machine is to use a high-energy-density laser beam to act on the surface of the material, to instantly vaporize or change the color of the surface material by focusing, and to control the path of the laser on the surface of the material to form the required persistence. Graphical markers. Since the laser laser engraving machine can print various characters, symbols and patterns, the size of the characters can be from millimeters to microns, which has special significance for the anti-counterfeiting of products, so it is widely used in the anti-counterfeiting market.

Before the large-scale application of laser engraving machine marking, the marking on the packaging is usually printed with ink. The marks printed by this traditional method tend to peel off over time, become blurred, easily tampered with, and cannot be used with high precision. Although it has advantages in equipment cost, the continuous cost of consumables (ink) is high, and it will cause some pollution to the environment.

The emergence of laser laser engraving machine has solved a series of problems brought by traditional ink printing. For food packaging, the use of laser marking has the advantages of non-toxicity, no pollution, high efficiency, high definition, exquisite patterns, and no falling off. In addition, laser marking can also be combined with computer technology, and by linking the database system, we can track and query the detailed information of the factory and circulation of food in time to ensure that we can eat with confidence.

The medical industry is inseparable from the escort of laser marking. Because medical products are in direct contact with the human body, it is related to the lives and health of the people, so the prevention and control of counterfeiting of medical products has become the top priority of protecting consumers' health.
